MATERIAL-MOVING APPARATUS.

Application filed December 5, 1917. Serial No. 205,587.

To all whom it may concern:

Be it known that L'Louis E. DIERKS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Material-Moving Apparatus, of which the following is a specification.

My invention relates to improvement in vmaterial-moving apparatus more particularly, though not exclusively, to apparatus of a type comprising, generally stated, an inclined cable-way supporting a traveling carriage thereon, with a scraper-bucket connected with the carriage, and a hauling line through the medium of which the movements of the carriage and bucket are controlled, the scraper-bucket being adapted to be filled at its forward end and to discharge, at the point of dumping, through its valve-equipped rear end.

As structures of this type have been usually constructed the bucket is so supported that it remains, during the opening of the valve at the dumping end of the bucket, in the dumping operation, in the same position it assumes in the movement of the bucket to dumping position.

As a result, either the bucket must be normally tilted to such a degree that objectionable friction is placed upon the gate at the discharge end of the bucket, in order that the bucket may discharge when operating ondifferent kinds of material, or if such undue tilting is eliminated to reduce the friction on the valve mechanism, the material, if of certain kinds, will not freely discharge from the bucket.

My primary object is to provide an apparatus of the general type above stated, which will reduce to the minimum friction against the gate tending to prevent its turning in the dumping operation, and which will insure the dumping from the bucket of the charge of material therein, regardless of the character of the material; and other objects as will be manifest from the following 'description.

Referring to the accompanying drawings- Figure 1 is a view in. side elevation of apparatus constructed in ccordance with my invention for transferring material from a lower to a higher elevation, the apparatus being...shown 1n the position 1t assumes 1m- Patented Apr. 23, 1918.

mediately before dumping or, in other words, during the load-carrying operation. Fig. 2 is a similar View showing the parts in dumping position.

Fig. 3 is a similar view of a modification of the construction shown in Fig. 1, showmg the apparatus in the position it assumes immediately before dumping; and Fig. 4,

a similar view, showing the apparatus of Fig. 3 in the act of, dumping.

Referring to the construction illustrated in Figs. 1 and 2, the inclined cableway com monly used in apparatus of this general type and forming a guide-way is represented at-5, this cable in practice being anchored at its lower end in any suitable manner, and at its upper end supported at a higher elevation and in a manner adapting it to be slackened and made tautat will, all as is well understood in the art and therefore does not require illustration. Slidably mounted on the cableway 5 is a carriage 6, which may be of any suitable construction, that shown comprising a pair of side frames 7, one only of which is shown, which arespaced apart at opposite sides of the cableway 5 and are connected together, as for example, by the cross-pins 8, 9, 10, 11, 12, 13 and 14:, with suitable spacers between these frames to hold them apart, as is common in constructions of this general character. The pins 8 and 9 form supports for sheaves 15 and 16, I".1)8CtlV6ly, which rest upon the cableway .Z. A dumping-scraper or bucket, represented at 17, and which is supported from the carriage 6, is provided at its forward open end with a cutting edge portion 18, adjacent to which is a bail 19,

and at its rear, open end portion is equipped I with a gate-valve 20 formed of a curved end-plate 21, which extends across the rear, open end of the bucket, and side-plates 22 at opposite sides of the bucket, at which the gate-valve is pivotally supported on the bucket as through the medium of pivots at opposite sides thereof, one of these pivots being represented at 23.

The main section of the hauling-line is represented at 24, this line, in practice, usually being wound upon ad'ruin or windlass for controlling the movements of the carriage upon the cableway. The section 24 is connected with a block 25, equipped with a sheave 26, this block being also connected its lower end in load-carrying position, The

cable 31 connects at its lower end with the' lower end of the valve 20,'thence passes upwardly around asheave 32 'on the cross-pin 10, thence over a sheave 33 on the pin 14, and thence under the sheave 26 to a travels ing-block 34, to which it is connected, this block carrying a'sheave 35, on which the block rollingly bears against and is support ed on, the cable 5, this block cooperating with a stop 36 on this cable for a purpose hereinafter described. The cable 31, intermediate the sheaves 26' and 33, is connected as indicated at 37 withone end of a cable 38, which passes over a sheave 39 journaled on the pin 13, the lower end of this cable connecting with the bail 19.

In the operation of the apparatus, the operator slackens the cable 5 and by drawing on the hauling-line 24 pulls thescraperbucket through the material to be transferred, the material filling the bucket. The cableway 5 is then drawnsufiiciently taut'to lift the bucket out of engagement with the material and the carriage and bucket are drawn up the cableway by pulling on the hauling-line 24, the bucket assuming the load-carrying position illustrated in Fig. 1.

In the movement of the carriage and bucket 17 up the cableway 5 movement of the block 34 is arrested by the block engaging the stop 36 and continued pulling on the hauling-line 24 therefore operates to cause the cables 31 and 38 to travel at twice thespeed of the cables 24 and 27, with the result of swinging the gate 20 upwardly to uncover the open, rear, end of the bucket and tilt the bucket on the cable 29 in counter-clockwise The construction illustrated in Figs. 3 and 4 is the same as that shown in the preceding figures except that instead of supporting the bucket 17 from the separate cables 29 and 30 it is supported from a single cable 40, which issecured at its opposite ends substantially at the same points as the cables 29. and 30 are connected with the bucket, and extends slidingly over a sheave 41 rotatably mounted on the carriage 6. In this construction the cable 38 carries a stop 42 adapted to engage the carriage 6 and prevent the bucket, when the parts of the structure are in the normal load-carrying position represented in Fig. 1, from tilting downwardly at its forward end to discharge position.

In the dumping operation effected by con inued pull on the hauling-line 24 after the block 34 engages the stop 36, the forward movement of the cables 31 and 38 relative to the haulingline.24, operates to raise the valve 21 and swing the bucket in counterclockwise direction as shown in the drawings .to dumping position, the cable 40 running over the pulley 41 in this operation.

It will be readily understood from the foregoing that while pressure of the material in the bucket against the valve 20 is reduced to the minimum, the feature of tilting the bucket as explained insures the discharge of the material from the bucket regardless of its character, and thereby theapparatus is caused to tilt with comparative ease positively. structions shown the bucket is maintained in load-carrying position even should the hauling-line become slackened as sometimes,

occurs in the hauling of the bucket to dumping position and thus accidental dumping is prevented. I

While I have illustrated and described two forms of construction in which my in- Furthermore in the particular c0n vention may be embodied, I do not wish to be understood as intending to limit it thereto, as the same may be variously modified and altered and the invention provided in other forms, without departing'from the spirit of my invention, it being my intention to claim, my invention as fully and 001m pletely as the prior state ofthe art will permit.
